Exit region event takes a long time to fire when app is in background

I tested the library-reference having modified it only to send notifications on each didEnterRegion and didExitRegion events (for better visualization).

Expected behavior

App is in background. Thanks to the fast BLE background scans (paragraph: background detections between scan cycles) i expect the following:

1. On entering a region i expect to receive didEnterRegion event in a matter of 10-15 seconds

2. On exiting a region i expect to receive didExitRegion event in a matter of 10-15 seconds

Actual behavior

On entering a region event was received in under 10 seconds, whereas on exiting it came only after 5 minutes. On tests that i did not record this time could raise up to 8-10 minutes.

Steps to reproduce this behavior

Steps are in a test report form. The device used in this test was Google Pixel 2 (Android 9).

1. 13:41:20 - app is in background
2. 13:43:20 - beacon was enabled.
3. 13:43:25 - got an enter event. App launched itself in a foreground, i almost immediately sent it back to the background. (see Log 1)
4. 13:48:58 - beacon was disabled.
5. 13:53:47 - got an exit event. (see Log 2)

Mobile device model and OS version

Tested on Google Pixel 2.0 (android 9) and Xiaomi Redmi 4X (android 7.1.2).

Android Beacon Library version

2.16.1

Conclusion

So, the question - when app is in background is it okay for the didExitRegion event to come only after 5-15 minutes? If so, why?

To better understand the use case - i am tracking the amount of time the user spends in a region. Thus, precision is of importance.

@KeyStarr, to make this easier to find, I added the table to a new page linked off of docs here

I also added some notes about testing #869 on that issue. You are welcome to try it, if you are up to compiling the library from source.

The table is great! But i meant including this info into the Docs section of the https://altbeacon.github.io/ , because otherwise it is not really searchable (or have i missed it there?).

The feature is for the e-commerce app, so it is not too important to disturb user with a permament notification nor to drain too much battery. But thank you for the suggestion!

However, i found your solution in #869 interesting. Could you, please, expand a bit more on why it isn’t reliable? Does it mean that it will improve precision only for some users while not introducing any other issues/crashes?
